“The Point of Evolution” started as a Mathober doodle and led to this GIF.
Dimensions are fun – what do you see? what do you notice?
Side Note: I talk about dimensions when covering combining like terms. One analogy – A 3D banana can’t combine with a 2D banana (or whatever noun seems to go with the variable you have). We have fun with expressions using various animals/objects and their dimensions. Variables (things) and their exponents (dimensions) need to match to be able to combine them.
